Erzi Tower Complex consists of eight military and several dozen residential towers. The height of some structures reaches 30 meters. Erzi translated into Russian means "eagle". According to one of the local legends, once the inhabitants of the village of Kerbita came to this place and cut down a tree. On it they saw an eagle's nest with chicks. So the settlement that appeared on this place was called Erzi. The eagle appears to have become a sacred bird to the local population.
